ANTEC 1200 Watt. ok for THREE GTX480'?

Theres a chap on here with 2 480's with a watt meter pulling 1100 watts so I'd be very careful, even if it will run them I'd stay away from furmark or overclcking them
 
Yes buttkinz, thats my main worry, overclocking all three of them, may be a bit too:)

i've seen someone run FOUR in quad sli on a Antec 1200 (youtube), but i think it was modded or something....
 
Some results of my system with a GTX 480:

615w with Prime & Fur Mark running
405w with Prime running
503w with Fur Mark running
272w Idle
 
On Gamespot UK there doing a feature "Greatest Gaming Rig" and there building a monolithic insane PC with 3x480s and 1 460 for physics and there powering that and quite a lot of other madness including 2xXeon CPUs on a 1200w so id say yes m8, with room to spare. I dont think people quite realize how insane 1200w actually is :/ Thats a lot of power, don't worry yourself it will be fine.

Makes you wonder if they've actually built & run it though :D
 
yes, just seen the three videos from you "link" Gantoris. waiting for it to be finished, but 3 GTX480's 2 Zeons, one GTX460, naaaa won't boot:)
 
lol, it'll boot and immediately gain sentience ushering in a robot apocalypse!

Im pretty confident it'll boot up and run just fine, tho would be freaking hilarious if they set it up, press power and it bursts into flames live on there show :)

Was a bit impolite of meh not to link so here ya go for those interested in this insane build...

Thats all so far, look forward to seeing what frame rates they get of that beast.

you may find that your rig wont run it still

we have had a lot of trouble running 480s in tri sli on low end X58 boards

high end boards like the rampage3/UD9 with pcie molex inputs are the way to go.
for any kind of reliability anyway.

i had three 480s all folding at 100% on a P6X58D-E and it killed the board after a week
then i put them on a UD7 and it killed that too.
just look at the distributed computing forum where people like Biffa run 4 fermi cards and get through loads of boards.

personally I cant see what you would gain from a third 480.
i use one card at 1900X1200 and it is ample for that res, stepping up soon to a 30" panel and it will probably run everything on a single 480 still but i am adding a second to keep fps consistancy up.

dual cards is more than enough for the res of your U2711 [excellent choice of panel btw :cool:]. even at the bumped up res of 2560x1600 on the 30" it would be overkill for most things.
i think your rig is quite well balanced personally, another 480 may be doable but £350 for a card that may throw up issues and will boost your fps from 70+ to maybe 90+ in the latest titles is a bit of a waste.

i would put that £350 to better use, you speak of a USB sound card, why not look at this? that way your system would be better rounded, you have more than enough graphics horsepower and that kit would compliment it perfectly. a better use of your funds in my opinion.

That would be me. (1158w :p )

That pic was taken with Furmark and Prime maxing out my watercooled and very highly overclocked system ([email protected], 480SLI@910core 4400mem), gaming tends to hit somewhere in the 800's on the same setup.

I have a Be Quiet! DPP 1200W PSU.

Yes, thanks RjK, good advise, really. Wasn't thinking about the MOBO limitations though, so cheers for that one. Will "settle" for two then:)

its probably best

like i say, that sound card/headset bundle is really good. you cant go far wrong with it and it will really add to games. in my opinion more than another gpu would add to your current setup.

plus it looks totally sleek ;)

Thats motherboards he means not graphics boards :p

To be fair that was only one mobo (and 1500W PSU) :) And the replacement had a nice molex on it to take the load off the 24pin 12V lines :eek: Well its been running well for a few months now.

But we are pushing it a bit hard compared to gamers or benchmarkers, certainly I'd say that folding work units hammer cpus harder than Prime95 and gpu's about as hard as Furmark, but 24/7.

But for the OP, for gaming stick with two, maybe get a GTS450 or GTX460 for Physx if you really need it. Or a better sound card.

But a 970/980 hex core overclocked is going to push near 250W, and each GPU will max out at around 300W so you just need to do the math and work out if you will ever be maxing out the CPU and GPU's for any length of time.
 
Rjkoneill speaks sence, there isnt a game in existence that would benefit from 3x480s and by the time there is you would want a new GPU anyway.
